Brad Sherman is a Congressman from California. That fact alone tells you that he’s a liberal kook.

Nevertheless, he emerged from hibernation like Punxsutawney Phil, but instead of predicting that winter was about to end, predicted that the end of the unpleasantries in Libya weren’t and suggested that the administration isn’t being, shall we say, truthful about the cost of its current kinetic military action.

A Democratic lawmaker said Thursday that the White House is “dramatically underestimating” the cost of the nation’s military involvement in Libya by relying on misleading accounting.

“That effort is costing us billions a week,” Rep. Brad Sherman, California Democrat and a certified public accountant, said in his opening remarks at a House Foreign Relations Committee hearing on reforming the United Nations with Susan E. Rice, U.S. ambassador to the United Nations.

Last week, Secretary of Defense Robert M. Gates testified that the nation’s initial involvement in establishing a no-fly zone over the skies of Libya carried a $550 million price tag and that the cost going forward would be about $40 million a month. He also assured lawmakers he had enough money in his budget to absorb the costs without asking Congress for new funding — though he wasn’t ready to say where exactly the money would come from.

But Mr. Sherman on Thursday said the estimates are based on what’s known as “marginal-cost accounting,” which doesn’t include costs for things such as overhead from the development of the weapons systems and equipment being used, or the salaries of the people involved in the effort.

“We need to use full-cost accounting,” Mr. Sherman said.

Full-cost accounting? We’ll get to full-cost accounting on Libya after we get it on TARP and the $timulus and Fannie and Freddie and a dozen other fiscal fiascos.
